The Output summed any number of edges as layers. That made it the only
sound input of its kind, and it read as if a note could be several
voices. A note was always one voice, but the graph did not say so.
Now the Output takes one sound like every other sound input, and
several are put together with a Mix in front of it (decided by the
user after #331).
- The Output's input is no longer `many`. A second edge replaces the
first, as at any data input.
- With only one drum sounding for a note, a Mix is its other side. A
drum kit keeps the volume of each drum.
- An instrument saved with several edges into the Output keeps them
but does not compile. The Output says "Takes one sound: put a Mix in
front of it to play several". No saved project has one: the only
instrument there (cbbf160bb7e8) has a single edge.
- An Output with nothing in it is a problem now, not silence.
- The compiler gathers only triggers from several edges. The player
still takes a list of layers, which an instrument fills with one.
Tests:
- instrument.test.ts: drum kit through a Mix, a second edge replacing
the first, an old Output with two edges, an empty Output (33 tests)
- Counter-check: `many` back on the Output turns 15 tests red, the
new one about the second edge among them
- e2e 34 on melektaus-atx: ALL PASSED, 47 checks
- Gate on melektaus-atx: CHECK EXIT 0, 244 test files, 3789 tests
